Tar :to continue , enter device/file name when ready or null string to quit.

I inserted new tape and entered "/dev/rmt/0m"
then i get message
User opened file /dev/rmt/0m to continue

after that it ended up with below error

Please suggest how to proceed.

you can use the "mt" command for example:

mt [ -f TapeName ] status

run the man on the mt command to see more options.

also you can do the following:

# diskinfo /dev/rmt/0m
SCSI describe of /dev/rmt/0m:
vendor: HP
product id: C1537A
type: sequential access
size: 1161216 Kbytes
bytes per sector: 1024
